Answer:

let cp of7 magazine =x

cp of 1 magazine=x/7

so of 1 magazine=x/8

loss=cp-sp=x/7-x/8=x/56

loss percentage=(x/56)r(x/7)*100=12.5 percent

Answer 2

Step-by-step explanation:

let CP of one magazine be rupee1.

SP of 8 magazine = CP of 7 magazine.

SP of 1 magazine=rupee 7/8

Loss=CP-SP

= 1-7/8

=8-7/8

Loss percent=loss/CP*100

=1/8/1*100

=1/8*1*100

=100/8

=12.5%
